Over at the DC Examiner, I argue that reforming Air Traffic Control will be a stimulus plan in itself, helping a struggling industry, reducing oil imports, and delivering real benefits to airline passengers. And, if that’s the sort of thing you’re into, it will also be extremely effective in lowering greenhouse-gas emissions. Sadly, it’s also the sort of policy that will never get off the ground without a strong presidential push, so no wonder it hasn’t been seriously advanced for over 20 years.
